It is official now: Russia's Supreme Court declared "extremist" and banned the "LGBT movement".

A single display of LGBT flag, offline or online, is punishable by a fine.
In case of multiple offenses, the punishment is up to 4 years in prison.
Activism, online or offline, and potentially donations to LGBT charities, are punished by up to 6 years in prison.
Allies of LGBT activism are now legally banned from elections.

And there is a new law coming up, "justification" of "extremism" online (as in, not denouncing), punishing it by a prison sentence of up to five years.
